[SOLVED] Udoo Neo won't boot anymore

I had to reinstall UDOObuntu Neo Basicks because of some problems. The steps I did to reinstall UDOObuntu:

1) sudo diskutil unmountDisk /dev/disk2
2) sudo diskutil zerodisk /dev/disk2
3) sudo dd bs=1m if=/Users/erje/Downloads/UDOObuntu_neo_basicks_v2.0beta3.img of=/dev/disk2
4) sudo diskutil eject /dev/disk2

But my Udoo Neo won't boot. When powered on the Green en middle Red led are on. The the outer Red led flashes twice and the middle Red led goes off. Only the Green led stays on. I can't login with the VNC viewer or ping the device.

What could be wrong?

 

Dear eRJe,
my first suggestion is to follow our guide for what concerns the reinstallation process.

 

Before I tried the steps in my first post, I have tried twice the regular tutorial. But also without success.

 

We'd like to examine it closely. Please open a ticket.

 

Solved by using different MicroSD card... seems the (new) MicroSD card was broken...
